Castellers Build Human Tower for Catalan Festival

Members of the "Castellers de Vilafranca" formed a human tower in Vilafranca del Penedès, Spain, to mark Saint Felix Day earlier this week. The building of human towers is common during festivals in Catalonia, when teams gather to compete against each other, building and dismantling "castells." Photo: Lluis Gene/AFP/Getty Images
